7. FABRICATION:

The Contractor / Agency is expected to perform fabrication in the best possible manner to meetthe requirements of design, drawing and specifications. The fabricated components shall meet

the tolerance requirements given in the Tender Document. The Contractor / Agency shall use

properly designed jigs & fixtures to ensure that there is no deformation or warping of surfaces /

members and components meet the requirement of straightness, fits & interchange ability.



6

Following general guidelines shall be followed by the Contractor:-

a) Straightening of Members:-

Before being laid off or worked in any manner, structural steel shall be straight, without twist,

bends or kinks, and if straightening is necessary, it shall be done by a method which shall notinjure the metal to ensure good welding and fitting of members. All steel shall be cleaned of

dirt, mill scale and rust prior to fabrication.

b) Shearing, Chipping and Gas Cutting:-

Shearing, Chipping and gas cutting shall be performed carefully and all portions of the work,

which will be exposed to view, shall present a neat appearance. Finishing of sheared or cut

edges of plates or shapes will not be required except as noted in these specifications.

c) Edges to be welded:-

The edges of plates and shapes to be joined by welding shall be properly formed to suit the

type of welding selected. Where plates and shapes have been sheared, edges to be joined by

welding shall be machined or chipped to sound metal. Plates and shapes to be field welded

shall have their edges prepared in the shop for the type of weld selected.

d) Bent Plates and Shapes:-

Where bending or forming of plates or shapes is required, the plates or shapes shall be bent by

cold forming. Heating and hammering to correct bends will not be permitted.

e) Welding :-

i) Welding Technique

Care shall be taken to see that the welds when being made are well accessible. Overhead

welding is to be avoided, if possible and flat position is to be strived for.

All welding shall be done by the electric arc method by a process, which will exclude the

atmosphere from the molten metal, except where otherwise specifically permitted. All welding

electrodes required shall be furnished by the Contractor. Correct selection of electrodes shall

be done taking due care of welding method and base metals of components.

The welding electrodes shall be of the heavily coated type designed for all position

welding. The make, type and size of all welding electrode shall be subject to the approval ofthe Engineer-in-charge.

In assembling and during welding, the component parts of built-up members shall be held

in place by sufficient clamps or other adequate means to keep all parts in proper position.

The surface to be welded shall be cleared of scale, slag, rust, paint, and other foreign matter.

Where weld metal is deposited in two or more layers, each layer shall be brushed with a wire

brush or otherwise cleaned before the subsequent layer is deposited. In welding, precautionsshall be taken to minimize stresses due to heat by using the proper sequence in welding.



7

Upon completion, the welds shall be brushed with wire brush and shall show uniform sectionsmoothness of weld metal. Edges, ends of fillets and butt joint welds shall indicate good fusion

and penetration into base metals. Specific requirements for butt joints and fillet joints are given below:

Butt joints: -In principle, butt joint should be made with back run. Should it be not possible to do the

back-run, either a backing strip should be placed or welding should be so made that the melted

metal fully penetrates to the backing strip. Dye- penetration test shall be carried out after each

pass of the butt weld.

The joints in the skin plate shall be staggered & preferable located near the point of contra

flexure. The edges of skin plate shall be prepared in shop. Skin plate joined by butt welding.

Dye-penetrant test shall be carried out for all butt welds. Joints, if required in horizontal

members of gate, the same shall be located sufficiently away from location of maximum

bending moments.

Fillet joints:-

All fillet welds shall be continuous. Fillet weld at‘t’ joint should be made, as a rule on each

side of the joint, unless it is otherwise agreed due to some practical reasons. Radiographic test

is not normally required for fillet welds. However, all fillet welds shall be checked by Dye penetrant test for soundness.

painting and surface preparation shall also conform to relevant Indian standard specifications,

IS: 14177/1994 with up-to-date amendment – Guidelines for painting system for Hydraulic

Gates and Hoist.

b) Preparation of surface:-

Surfaces requiring blast cleaning should be sand / grit / shot blasted after fabrication to class B

of IS: 14177/1994 with up-to-date amendment, prior to painting. Heavy deposits of grease or

oil may be removed by the solvent like clean mineral, spirits, xylol or white gasoline, etc, priorto sand blasting. Small quantities of grease or oil may be removed by the blasting process in

which case, however, the abrasive should not be re-used if it contains sufficient oil or grease to

render it unsuitable for blast cleaning purposes. The average surface roughness after sand-

blasting should not exceed 40 microns. Blast cleaning should be performed with sand / grit /

shot as per requirements given in IS: 1477 Part I/1971 after blast cleaning, the surface should

be cleaned from loose dust and debris preferable by air blast with the help of blower.



8

Other surfaces shall be prepared in accordance with the following procedure:-

i) Weld spatters or any other surface irregularity shall be removed by any suitable means before cleaning. All oil grease and dirt shall be removed from surface by use of clean

mineral spirit, xylol or

ii) white gasoline (lead free) and clean wiping materials.iii) Following the solvent cleaning, the surfaces to be painted shall be cleaned of all rust, mill

scale, and other lightly adhering objectionable substances by wire brush.

Surface of stainless steel, nickel, bronze and machined surface adjacent to metal work

being cleaned or painted shall be protected by masking tape or by other suitable means duringthe cleaning and painting operations.

Primers shall be applied as soon as the surface preparation is complete and prior to the

development of the surface rusting. The time gap between the application of the primer and

surface preparation shall normally not exceed 6 hrs. if there is considerable time gap, the

surface should be re-blasted prior to priming.

c) Shop Painting Details

a) Stainless steel and bronze surfaces shall only be cleaned but not painted.

b) All surface of the embedded parts like sill beam, which are to come in contact with

concrete, shall be cleaned as mentioned above and given two coats of cement latex to prevent

rusting during shipment and while awaiting installation. Over the prepared surfaces of

embedded parts (exposed surfaces), gate leaves, fulcrum.

c) Assemblies & levers systems, one coat of inorganic zinc silicate/zinc chromate should be

applied giving a dry film thickness of 70 ± 5 microns. The primer coat shall be followed by

finishing coat, which shall consist of one coat of.

d) Solvent less coal tar epoxy paint. The coat gives a minimum dry film thickness of 150 ± 5

microns.

e) All finished surfaces of ferrous metal including bolts, screw threads etc., that will be

exposed during shipment or while awaiting installation shall be cleaned and given a heavy

uniform coating of gasoline, soluble rust preventive compound or equivalent.

f) Field painting

The painted metal work shall be handled with care so as to preserve the shop coats. Thearea of the shop paint, which has been damaged during transport shall be cleared to based

metal and repainted. Paint applied t such areas shall be of the same type as used originally in

shop painting.2 finishing coat of solvent less coal tar epoxy paint having minimum dry film

thickness of 150 ± 5 nd microns shall be applied after erection of gates at site. The total dry

film thickness of all the coats including primer coats shall not be less thane 350 microns.
